Perhaps you should try some spelling variations:
"modified parameters optimization algorithms" » "modified parameter optimization algorithms", "modified parameter estimation algorithms", "modified parameters optimisation algorithm", "modified parameters estimation algorithms", "modified parameters estimation algorithm", "modified parameters optimisation algorithms", "modified parameters estimation algorithmss"
"modified qoe optimization algorithm" » "modified qoe optimisation algorithm", "modified qoe estimation algorithm", "modified qoe estimation algorithms", "modified game optimization algorithm", "modified _ optimization algorithm", "modified stage optimization algorithm", "modified male optimization algorithm", "modified bi1 optimization algorithm"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified qoe optimization algorithm\") OR (\"modified parameters optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified qoe optimization algorithm ) OR ( modified parameters optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified qoe optimization algorithm") OR ("modified parameters optimization algorithms"))*.
